Rear Brake Issue

My rear brake seems to stick after a short ride and I have to let it cool before I can ride again it is not very old it is off of a 2007 zx10r with under 3000 miles when the bike is up in the air the wheel spins free and the brake stops was wandering if the brake line has failed its a stainless line with the plastic liner its been a pain in the butt . thanks Joe

BigblockT, Chances are, either your' brake pedal/rod are adjusted to the point where the master cyl. piston can no longer return home (exposing the bleed back hole inside bore,) or said passage is blocked. Take care. heat transfer to fluid is a natural function, and brake fluid like everything else expands w/heat.get it hot enough and it could lock rear brake. luck G
